1-Methyl-1H-pyrazolo3,4-dpyrimidin-4(5H)-one

摘要

The title molecule, C6H6N4O, is essentially planar [dihedral angle between the rings = 0.46 (9)°]. The crystal structure consists of sheets of molecules lying parallel to (overline{1}11) formed by a combination of N—H...O, C—H...O and C—H...H hydrogen bonds. The sheets are connected through π–π stacking interactions.
